The least common factor of any set of numbers is 1.

I'm not sure what you mean by lowest common factor, typically math teacher will ask for least common multiple or greatest common factor on your homework.While the lowest common factor is 1, 1 is also the greatest common factor. The least common multiple is 640.

The least common multiple is 30. The greatest common factor is 3.

The least common multiple of two numbers is their product divided by their greatest common factor. Since 7 is a prime number and 27 is not a multiple of 7, their greatest common factor is 1. The least common multiple is 7 x 27 ÷ 1 = 189.

The least common multiple of the numbers 48 and 30 is 240 and the GCF is 6.
